This year, we marked Earth Day with a public lecture titled “Secrets of Seagrass Meadows” at the City Library and Reading Room in Mali Lošinj.

The lecture on the importance of the marine flowering plant Posidonia was delivered by our dear guest, marine biologist Barbara Čolić from the Marine Explorers Society “20.000 leagues”. Through a presentation of numerous photographs and videos, she brought the audience closer to the importance of Posidonia—a seagrass species that plays a key role in preserving biodiversity, protecting coastlines, and regulating the climate. The researcher spoke about the biology and ecology of Posidonia, the research being conducted, the methods used, and the results obtained, as well as the challenges this key species faces in the Adriatic. The photographs—as well as the new insights about Posidonia for most of those present—further enriched the lecture and sparked strong interest in this highly important topic. Particular attention was drawn to images of local bays familiar to the audience in Lošinj, which further highlighted the value of this habitat in our immediate surroundings.

The Blue World Institute, with the support of the organization Seacology, continuously works on the protection of Posidonia through various research, educational, and public activities. This lecture is part of a broader series of events aimed at raising public awareness about the importance of preserving seagrass meadows.

We also take this opportunity to announce an event called Posidonia Day, which will be held on May 15 in Mali Lošinj and will be entirely dedicated to this exceptionally important marine seagrass. Throughout the day, a series of educational and interactive activities for all ages is planned, with the aim of further bringing this topic closer to the general public.
